IMPROVEMENT IN JOURNAL-BOX LININGS.

PATENT 0 Specification forming part of Letters Patent No. 138,644, dated May 6, 1873; appl i ation filed January 29, 1873.

To all whom 'it may concern:

Be it known that I, STUART GWYNN, of the city, county, and State of New York, have invented a new manufacture, the same being an Improved Lining for J ournal-Boxes and other rubbing surfaces, of which the following is a specification, reference being had to the accompanying drawing forming part of the same.

On the 12th day ot April, 187 0, certain Letters Patent of the United States were issued to me, numbered from 101,862 to 101,869, inclusive, for certaincompositions of matter denominated meta-line,7 and for the process or method of making the same, as also the ofiices it performs, t0 which reference is made.

The invention herein intended to be described and claimed relates to a special mode of applying the said several kinds of metaline, or any of them, or their equivalent, torpractical use; and consists in a combination of metall ine with the material, in the manner and for the purpose particularlyr described.

Fgure 1 is an edge view of a vertical sec; tion of a perforated plate of metal, the perforations being filled with powdered metaline or its equivalent. Fig. 2 is asurface view of the same in perspective. Figs. 3 and 4 are, respectively, similar views of the same sheet after it has been subjected to pressure and thereby completed.

In carrying out my invention, Itake a plate of metal, preferably copper or` y rass, and perforate it with numerous hol the perforations being from a sixteenth t inch in diameter,or larger, if sired. I then lay the sheet down upon a il` t surface, and till the perforations with powered metaline or its equivalent. The plate i 1 hen to be subjected to severe pressure, pre rably between rollers, whereby the plate is r o need in thickness at the same time that th duced and compacted into a s id mass. The rolling ofthe plate will spre` the metal at the opposite surfaces somewh` more thanin the center, giving theapertu 2 s,` in some degree, the shape seen in Fig.'3, m ereby the metaline is securely confined in t apertures.

Sheets thus made may be c t into any desired forms, to be used in linin journal-boxes or forming other surfaces desil ned tobe subjected to friction, the metalin being a material which, in its action as su `s surfaces, obviates the necessity of the usof oil or any other extraneous lubricator. g

What I claim as a new manl facture isf- A perforated sheet of meta with which is incorporated metaline, subst t'ially as and for the purposes specified. l
